Move over Mariah Carey. Brenda Lee is the new Christmas Queen of the Charts.

Ms. Lee’s “Rockin’ Around the Christmas Tree” tops the Billboard Hot 100 this week, 65 years after the now 78-year-old Ms. Lee recorded it.

Both Ms. Lee’s age and the gap between the song’s first charting and its reaching No. 1 are all-time records for the Hot 100, the gold standard of U.S. music charts.

“Rockin’ Around the Christmas Tree” also ends a run of frustration, having reached No. 2 several times in recent Decembers for a total of nine weeks, all behind Ms. Carey’s “All I Want for Christmas Is You.”

According to a report at Stereogum, “Rockin’ Around the Christmas Tree” may have been helped by Ms. Lee doing promotions, including the song’s first official music video and “a TikTok campaign in which she discusses her career.”

She also is scheduled to perform the song Thursday on the NBC special “Christmas At The Opry.”

The popularity of streaming and its being factored into the numbers that get crunched into Billboard’s weekly charts — traditionally based on single-record sales and radio stations’ airplay — has given Christmas-season hits a much greater presence in the last half-decade or so.

The majority of this week’s Top 10, in fact, is Christmas songs: Ms. Carey at No. 2, Bobby Helms’ “Jingle Bell Rock” at No. 4, Wham’s “Last Christmas” at No. 5, Burl Ives’ “A Holly Jolly Christmas” at No. 6, and Andy Williams’ “It’s the Most Wonderful Time of the Year” at No. 10.

“Rockin’ Around the Christmas Tree” is Ms. Lee’s third No. 1 hit after “I’m Sorry” and “I Want to be Wanted,” both from 1960.

The 4-foot-9 singer was dubbed “Little Miss Dynamite” when she had a string of 27 Top 40 hits from 1959 through the mid-1960s. Her pop chart success largely ended with the British Invasion, but she became a regular on the country Top 10 in the 1970s and 80s, including hit collaborations with George Jones and the Oak Ridge Boys.
